Ethanol can be converted into ethanoic acid by_________________?
Correct answer: C. Oxidation
- A. Hydrogenation
- B. Hydration
- C. Oxidation
- D. Fermentation
Explanation
Ethanol becomes ethanoic acid when it is oxidised, usually with acidified potassium dichromate or potassium permanganate: the primary alcohol first forms ethanal and then ethanoic acid. Fermentation produces ethanol from sugars, so choosing fermentation reverses the direction of the process.

About Alcohols
Alcohols contain a hydroxyl group attached to a saturated carbon atom and are classified as primary, secondary or tertiary. Their nomenclature, hydrogen bonding, acidity, oxidation, dehydration, reaction with sodium and conversion to haloalkanes are covered, along with the distinction between alcohols and phenols, where the hydroxyl group is attached directly to an aromatic ring.
